If anyone can solve them for me I'd be really thankful. I have to take an exam soon and I can't get past these stupid 3 problems! It's driving me crazy. An answer has to be rounded 3 decimal points. Example: .038

These problems have to do with the multiplication rule and such.

1. License plates in my city consists of 3 letters followed by 3 integers. Repeats are allowed. If I select a license plate at random, find the probability that it has the letter J on it.

2. I will randomly rearrange the first 11 letters of the alphabet. Find the probability that the rearrangement has no vowel in the first five places.

3. I roll a fair die 4 times. Find the probablity that I see a "2" or "3" on both the first and last roll.

If anyone can solve these, you are a god.
